We investigated the flow behaviour of colloidal charged-sphere suspensions using a newly designed integral low-angle super-heterodyne laser Doppler velocimetry instrument, which combines the advantages of several previous approaches. Sample conditions ranged from strong electrostatic interactions with pronounced short-range order to individual particles with no spatial correlations. The obtaine...

there have been increasing interests in finding new and innovative solution for removal of contaminants from soils recently. in the present investigation, electro kinetic (ek) process coupled with activated carbon barrier to remove nickel from kaolinite clayey soil is investigated. laboratory tests were performed by applying a constant voltage to nominal electric field strength of 1 and 1.25 v/...
